Heat index

In December, the heat index is calculated to be a scorching 41°C (105.8°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Note: The UV index of 7 during December leads to these advisories:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
